We can get a contact information for any contact from contact list of an Android Device easily. For this follow the steps below:

1. Write the permission to read Contact's data into your AndroidManifest.xml

   copytext

   <uses-permission android:name="android.permission.READ_CONTACTS"  />

   <uses-permission android:name="android.permission.READ_CONTACTS"  />
   

2. Write the below code within your activity from where you want to perform action.

   copytext

   Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
   startActivityForResult(contactPickerIntent, 1001);

   Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);
   startActivityForResult(contactPickerIntent, 1001);
   

3. Also in your Activity, write the below code inside the onActivityResult method to listen for the result of step 2.

   copytext

   if(resultCode==RESULT_OK && requestCode==1001)
   {
   String ContactInfo = null;
   Uri uriOfPhoneNumberRecord = data.getData();
   String idOfPhoneRecord = uriOfPhoneNumberRecord.getLastPathSegment();
   Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?", new String[]{idOfPhoneRecord}, null);
    
   if(cursor != null) {
       if(cursor.getCount() > 0) {
           cursor.moveToFirst();
           String formattedPhoneNumber = cursor.getString( cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA) );
           String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
    
    
   StringBuffer s=new StringBuffer(formattedPhoneNumber);
       for(int j=0;j<s.length();j++){
           if(s.charAt(j)=='-')
           {
               s.replace(j, j+1, "");
           }
       }
       ContactInfo = "Contact:\n".concat(contactName.concat("\n"+s.toString()));
       Log.d("Varta", String.format("The selected phone number is: %s", ContactInfo));
   }
   cursor.close();  
   }
   }

   if(resultCode==RESULT_OK && requestCode==1001)
   {
   String ContactInfo = null;
   Uri uriOfPhoneNumberRecord = data.getData();
   String idOfPhoneRecord = uriOfPhoneNumberRecord.getLastPathSegment();
   Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?", new String[]{idOfPhoneRecord}, null);
   
   if(cursor != null) {
       if(cursor.getCount() > 0) {
           cursor.moveToFirst();
           String formattedPhoneNumber = cursor.getString( cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA) );
           String contactName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
   
   
   StringBuffer s=new StringBuffer(formattedPhoneNumber);
       for(int j=0;j<s.length();j++){
           if(s.charAt(j)=='-')
           {
               s.replace(j, j+1, "");
           }
       }
       ContactInfo = "Contact:\n".concat(contactName.concat("\n"+s.toString()));
       Log.d("Varta", String.format("The selected phone number is: %s", ContactInfo));
   }
   cursor.close();  
   }
   }
